Look through the titles of the patents that show-up in your search. If there are any patents that look like they might be relevant, based on the title, click on the patent number or title. Then click on the "Images" button to see the actual patent and any drawing figures.
If there are too many titles to look through (over 100 or so), then you might remove some of the wildcards and synonyms from your strategy that are more borderline. If there are too few titles to look through (fewer than, say, 10), you might add wildcards or keyword synonyms.
If you run across a few patents that are dead-on hits, then there are almost certainly more relevant patents out there. But you might not need to find them... your search might be over. If you found an identical patent (like I did on my first invention in 1990!) then you can stop. But don't be discouraged! You are a creative person, as evidenced by the fact that you had this idea in the first place. If you find that your idea already has a patent on it, know that your idea was patentable! That's a great sign! It means you've got an inventive personality and you'll no-doubt come up with something else soon.
If you didn't find anything "out in the open," there still might be a relevant patent lurking under some rock somewhere. On the other hand, there may not be. So at this point you should conduct the next step, the Do-It-Yourself Market Search, and see if there is a product (that is not necessarily patented) that is being offered for sale that is similar to your idea.
If you still don't find anything, it's time to call-in the experts to really look under those rocks and have a Professional Patent search conducted on your behalf.
